Florida-based `Nature` Films To Air

Nature, the Public Broadcasting Service`s natural history series, broadcasts two Florida segments -- one live, one videotaped -- this weekend. Both center on birds of Florida.

Today at 5 p.m., a crew of 20 (including Nature host George Page) broadcasts a live, one-hour episode from Anhinga Trail in the Everglades. On Sunday at 9 p.m., a taped episode presents a compilation of footage from a week that the Nature crew was in the state. Miami/Fort Lauderdale PBS station WPBT-Ch. 2 and WXEL-Ch. 42 will air the live telecast at 5 p.m.; Channel 42 will show Sunday`s segment at 8 p.m.

Today`s Nature segment will be beamed to Great Britain by satellite, in addition to its live, nationwide U.S. telecast (Nature is co-produced by the British Broadcasting Corp.). It is Nature`s first national, live telecast in the program`s history. A spokeswoman for the program said Nature producers expect the live telecast to record ``anhingas, herons and egrets feeding their young in preparation for nightfall.``
